To analyze the statement about Colin's survey results, let’s summarize the data first:

  • Math: 14 students
  • Language Arts: 7 students
  • Earth Science: 10 students
  • Life Science: 11 students

Now, let's calculate the totals for Science and Math fans:

Total Science Fans:

  • Earth Science: 10 students
  • Life Science: 11 students
  • Total Science Fans = 10 + 11 = 21 students

Total Math and Science Fans:

  • Math: 14 students
  • Total Science Fans: 21 students
  • Total Math and Science Fans = 14 + 21 = 35 students

Now, let's evaluate each statement:

  1. The ratio of science fans to language arts fans is 10:7.

    • Science fans = 21, Language Arts fans = 7.
    • Ratio = 21:7, which simplifies to 3:1 (not 10:7). This statement is false.
  2. The ratio of language arts fans to science fans is 1:3.

    • Language Arts fans = 7, Science fans = 21.
    • Ratio = 7:21, which simplifies to 1:3. This statement is true.
  3. The ratio of math and science fans to language arts fans is 24:7.

    • Math and Science fans = 35, Language Arts fans = 7.
    • Ratio = 35:7, which simplifies to 5:1 (not 24:7). This statement is false.
  4. The ratio of language arts fans to math and science fans is 5:1.

    • Language Arts fans = 7, Math and Science fans = 35.
    • Ratio = 7:35, which simplifies to 1:5 (not 5:1). This statement is false.

Thus, the only true statement is:

The ratio of language arts fans to science fans is 1:3.
